I'm only recently in this forum and this is my first post. But in this time I've seen already a lot of lathe users looking for a free CAM program.

So I would like to inform you about my free program GrblGru. It provides CAM functionality and 3D simulation for milling machines and lathes. In command mode (G-code sender) it can communicate with GRBL as well as TinyG.
I use the program for my little DIY milling machine and my old lathe, that I've updated to CNC. Now I'm looking for good ideas to improve it.

If you like to give GrblGru a try, you can download it from my dropbox at https://goo.gl/quFpdZ
It's running under windows operating systems since XP.

On my youtube channel you can follow the history of GrblGru from the beginning in 2014 until now.
For lathe users maybe

gives you a good imagination about how GrblGru is working. Also my latest video, attached below, shows a large wood lathe in simulation mode.
For milling machine owner maybe my DIY 4th axis is interesting

Any suggestions for improvements and also critique are welcome

Have fun with GrblGru :)
